75481-73-1 Usage
Antimicrobial activity
A semisynthetic cephamycin. Activity is similar to that of
cefoxitin and cefotetan, but the activity against enterobacteria
and B. fragilis is somewhat better . C. difficile
is inhibited by 4–16 mg/L. It is stable to the common
β-lactamases of enterobacteria and Bacteroides spp.
A 15-min intravenous infusion of 1 g achieves a serum concentration
of 30 mg/L after 1 h. The plasma half-life is c. 2 h
and around 68% is protein bound.
Its safety profile and uses are similar to those of other
cephamycins. It is available in Japan.
Check Digit Verification of cas no
The CAS Registry Mumber 75481-73-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,8 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 75481-73:
(7*7)+(6*5)+(5*4)+(4*8)+(3*1)+(2*7)+(1*3)=151
151 % 10 = 1
So 75481-73-1 is a valid CAS Registry Number.
